Thanks for all the comments
Any comments on ease of unbolting of headers?
Did any shear off??

12mm deep well socket.

I've removed tons of K exhausts and never had any of the header flange bolts shear.

Worst case the nut is stuck and it unscrews the bolt into the head. Not a big deal.

You might want too consider putting in fresh header gaskets when you reinstall.

+1 on the frozen nuts. They're copper and somehow seize to the steel bolt.
Heat them to a pretty glowing red color (mapp gas torch does a nice job) and they'll come right off and leave the stud in the head.
BMW stealer had new nuts in stock, if that tells you anything

I just squirted mine with penetrant, and they came right off with everything cool. I did replace the 4 gaskets and all 8 nuts with the new copper ones. I needed a ratcheting wrench for one of them sockets got the rest.

I have a whole, 'uncracked' exhaust in excellent condition, with new copper rings, o2 sensor for sale on on ebay...if your interested let me know.

I welded the exhaust on my bike...2-3 times? it kept cracking, and it was a going to be a temp. fix, so I bought this exhaust. I never used it, and just recently sold the K1100...so have some parts for sale.

About welding, do it on the bike unless you have a jig to to 'hold' header pipes etc. I had to heat and bend a pipe in order to even get it to fit back on bike, and it wasn't easy.

Thanks again.
Got 2nd hand unit from Motorworks today.
125 + studs, gaskets and rubber bits.
As against 600 for Remus.

I'm in Ireland 552255, so Nebraska a bit far to ship Smile
But thanks anyway.

The heat shield on my own is better than the s. hand.
Is it possible/easy to change it??

It's mounted on the lower mid left transmission bolt. Not too hard to get to when you have the exhaust off.

Apologies - I meant the chrome cover on the muffler.(can/silencer Smile )
It seems to be held on by pop rivets.
Can't have people thinking I did the damage Very Happy

And there's a fibre washer on the bracket at the box.
Spose it stops the rubber mount getting cooked.

Thanks Jim
4 studs on the bits box - 4 studs in head.
One won't move I reckon, took a lot of pull to get nut off.

Just studying joints in pipes - 2 broken off. The pipes aren't welded all around at all in original. The centre of the group is open!!!

Tried to get chrome cover off no move.
Must be on with heat. I ground the old one inside and can see the second metal underneath.

Have new - nuts studs gaskets rubber bits.

All back on.
Had to clean out sockets for studs as new wouldn't
go in. Old ones would only go into one socket.

Thanks for all the help

Still couldn't get chrome cover off.
